Description

Electromechanical Transducer Device {ELECTROMECHANICAL TRANSDUCER DEVICE}

The present invention relates to an electromechanical transducer device for controlling one or more functions of a vehicle transmission or drive arranged physically separate from the transducer.

BACKGROUND OF THE INVENTION Electromechanical transducer devices for controlling the function of a drive of a vehicle or a vehicle transmission, such as a gearshift lever, which can be moved into various movement positions, are known in the prior art. As regards the gearshift lever for manual or automatic transmission, it is common to equip a plurality of different Hall sensors to detect various shifting positions such as P, N, R, D of the gearshift lever. It is a practice. In this known technique, the circuit board is arranged parallel to the swiveling shaft of the lever, and the circuit boards are provided with individual Hall sensors located at a constant distance from each other.

Here, the arrangement of Hall sensors is formed such that each individual Hall sensor can detect any particular position of the gearshift lever and the selector lever. The Hall sensors are also configured to generate a binary signal that provides information as to whether a magnetic element arranged on the gearshift lever or the selector lever is located opposite from the Hall sensor. A plurality of Hall sensors located at a constant distance from each other must be arranged to be distributed over a relatively large surface area, and the plurality of Hall sensors must be electrically connected so that all imaginable movement positions of the gearshift lever can be clearly detected. do.

German utility model DE 20 2007 000 210 U1 describes a shift-by-wire actuator for automotive transmission. The apparatus consists of a gearshift lever mounted on a first shaft by a gearshift lever receptacle. On a bearing journal of the gearshift lever receptacle, a permanent magnet is arranged which cooperates with a hall sensor positioned opposite to directly detect the angular position of the gearshift lever.

European patent application EP 0 075 693 A1 discloses that the position of the gearshift lever can be detected in a contact-free manner by magnets attached to the gearshift lever and by magnet-sensitive sensors. Describes a speed selector for a transmission. One dedicated sensor is provided for each gearshift lever position to be determined, or a separate magnet sensing sensor is arranged in the apparatus such that fewer sensors than the number of gears are provided, and then the positions of the gearshift levers are respectively determined. Can be detected according to the code from a combination of sensors activated in the case of.

The drawbacks of such prior art transducer devices are the use of a plurality of Hall sensors and the relatively large surface area of the circuit board connected with the Hall sensors. In particular, this drawback is undesirable in that the installation space of the automobile is not sufficient.

In addition, such position-detection devices, which are generally fitted in the art, must be applied individually according to the shape and arrangement of the gearshift lever or the selector lever. As a result, circuit boards that are specially formed and applied in a given environment are always needed for different vehicle types with different gearshift levers and selector levers. The above has proved to have many drawbacks, especially in the case of a wide range of gearshift levers or selector mechanisms with gearshift levers of different lengths. In particular, when the steering wheel position of the vehicle is deformed from left to right (or right to left), the arrangement and configuration of circuit boards that conform to this deformation in terms of the gear shift or the selector lever is required.

Therefore, the present invention is simple in structure and easy to install, and in particular, has high reliability in detecting shift positions of the gear shift lever and the selector lever, has a small number of sensor elements, and is widely used in various types of transducer devices. It is an object to fabricate a simplified transducer device for driveline / transmission control of a motor vehicle that can be used and manufactured at low cost.

The object based on the present invention is realized by the transducer device according to claim 1. Preferred embodiments of the invention are described in the dependent dependent claims.

The transducer device according to the invention is formed for controlling one or more functions of an automobile transmission or drive arranged physically separate from the transducer, the device being a lever that can be operated to rotate around one or more first shafts. The lever is mechanically separated from the transmission or drive to be operated. This allows the setting movement or set position of the lever to be converted into an electrical signal, after which the signal is used to control the function of the transmission or drive. The lever of the transducer device is mounted on the first shaft by a suspension, the shaft having the first part of the rotation angle sensor device on an end section lying inside the suspension, and directly inducing the rotational movement of the lever or the angular position of the lever. For the purpose of detection, the first part faces the end section of the shaft and cooperates with the second part of the rotation angle sensor device arranged on the suspension. In the present specification, the present invention basically states that instead of having a plurality of Hall sensors arranged physically separate from each other, a single rotation angle sensor detects rotational or turning motion as well as the angular position of the lever, Each position is correlated with a predetermined setting position by an electronic evaluation unit located in the). The terms for the first part and the second part of the magnet rotation angle sensor device refer to pairs of corresponding elements of the parts, namely the rotation angle sensor and the magnetic element generating the magnetic field. In this specification, it is not important that any two parts are arranged on the suspension and which two parts are arranged on the shaft which constitutes the point of rotation.

The suspension extends substantially perpendicular to the first shaft and is formed to secure the bearing bolts fixedly coupled with the lever operated by the user. In the present specification, the circuit board fixing the rotation angle sensor is arranged directly on the suspension itself. The circuit board has one or more flanged extensions that protrude approximately from the surface of the circuit board so that one or more rotation angle sensors can be arranged on the extensions. In this specification, in particular the surface normal of the extension and the surface normal of the rotation angle sensor arranged on the extension extend substantially parallel to the first shaft. As a result, the pivoting motion of the suspension relative to the first shaft as well as the resultant angular position of the lever forcibly guided on the suspension relative to the first shaft can be detected precisely and clearly.

According to a first preferred embodiment of the invention, one single rotation angle sensor is provided for detecting the rotational movement or the angular position of the lever with respect to the first shaft. In this embodiment, the rotation angle sensor is formed internally and is formed of an integrated circuit. The rotation angle sensor may have a plurality of elements based on a plurality of magneto resistive elements and a Hall effect, which elements are electrically coupled to each other and within each other within a circuit board or sensor element. It is possible to clearly obtain information about the relative orientation of the rotation angle sensor with respect to the magnetic field externally exerted by an electrical signal which can be oriented differently with respect to the pick-up.

In particular, the individual magnetoresistive elements of the angle-of-rotation sensor are called so-called GMR elements or AMRs that use so-called giant magneto resistive effects or anisotropic magneto resistive effects to detect or quantify the magnetic field. It can be formed into an element. In particular, a sensor is provided with a so-called 360-sensor, which provides a clear electrical signal corresponding to each set position of the magnet element and the set angle for each position. Additionally or alternatively therein, the rotation angle sensor may have individual Hall elements in which the integrated circuits provided according to the invention are electrically coupled to one another instead of the magnetoresistive elements, based solely on the use of the Hall effect.

By providing one single angle of rotation sensor in the area of the rotation axis of the lever or the suspension that secures the lever, it is advantageously possible to be implemented without a plurality of Hall sensors physically separated from one another. The electrical signal that can be generated by the rotation angle sensor yields direct information about the angular velocity or current position of the magnet element mechanically coupled to the lever or suspension or magnetically coupled to the rotation angle sensor.

In addition, advanced devices for a single rotation angle sensor can significantly reduce the electrical circuitry required for the detection of rotational or swinging movements. As a result, it is no longer necessary to electrically couple a plurality of individual sensor elements, for example a plurality of Hall sensors, but instead the output of a single rotational angle sensor with Should be combined, this measuring unit can detect the angular velocity and / or rotation angle of the lever as a function of the frequency of the signal generated by the rotation angle sensor or the amplitude of the signal.

The device of the rotation angle sensor formed in the adjacent vicinity of the swivel shaft realizes the advantage that the detection of this position or angle is completely independent of the actual shape of the lever which can rotate around the shaft. As a result, the device according to the invention can be generalized according to all kinds of shapes of the transducer device. In such a device it is also no longer suitable for the transducer device to be provided in a variant with a steering wheel on the left or right side of the motor vehicle. In addition, it is possible to be formed without a circuit board which is preferably formed parallel to the axis of rotation of the lever, thus saving valuable installation space.

According to another preferred embodiment of the invention, the first component of the rotation angle sensor device is formed of a magnetic element that generates a magnetic field, and the second component of the rotation angle sensor device is formed of a rotation angle sensor. Originally, the magnetic element has a magnetic north pole and a magnetic south pole that break the symmetry of the shaft to which the suspension is attached. In this specification, in particular one of the components of the rotation angle sensor device, in particular the magnetic element generating the magnetic field, is arranged so as not to rotate on the plane of the end section of the shaft and on the surface of the corresponding other component, ie the rotation angle sensor It is arranged on the suspension in an imaginary axial extension of the shaft.

Here, the shaft itself or the bearing bolts of the shaft can be arranged fixed relative to the chassis of the motor vehicle, such that any rotation of the rotation angle sensor with respect to the fixed magnet element causes the generation of a signal that can be measured. . Naturally, the opposite shape is feasible, the sensor itself is arranged to be fixed relative to the chassis of the motor vehicle, and the magnetic element facing the sensor is pivoting or rotating. After all, in order to determine the rotation angle or position, an important point is the rotational motion between the rotation angle sensor device, the magnet element and the elements consisting of the rotation angle sensor.

According to another preferred embodiment according to the invention, the rotation angle sensor is formed substantially flat, in particular on a circuit board, the rotation angle sensor being oriented towards the surface normal of the magnetic element, the normal of the magnetic element being The magnetic element is substantially parallel to the first shaft on which it can be arranged. In this embodiment, the rotation angle sensor may be arranged parallel to the shaft off-center. However, preferably, the rotation angle sensor can be arranged in an axial extension with respect to the shaft and to form a flush.

Optionally or additionally for redundancy purposes, a magnet element is arranged on the shaft, and the sensor is oriented relative to the shaft on the lever and suspension such that its surface normal faces radially with respect to the shaft. Here, the relative motion between the rotation angle sensor and the magnet element is also clearly detected, converted into an electrical signal corresponding to the angular position, and relayed to the measuring unit located below.

Furthermore, according to the invention the lever passes through a slot of the suspension at a radial distance from the first shaft, the slot extending in parallel with the axial extension of the first shaft and the rotational movement of the lever about the second shaft relative to the suspension. To qualify. Therefore, the pivoting movement of the lever, which can be initiated by the user using the first shaft as the axis of rotation, in particular in the region of the slot guide, is transmitted to the pivoting movement of the suspension oriented perpendicular to the longitudinal extension of the slot. Transducers are provided.

The slot guide therefore directs the lever by the first shaft, which is the axis of rotation in which all rotational movement is transmitted to the suspension at a substantially one-to-one ratio. The slot guide thereby performs a carry-along function on the first shaft, which is the axis of rotation. In the direction perpendicular to the slot guide, the lever itself is provided to be rotatably hinged on the suspension using the second shaft with the axis of rotation. The second rotational movement causes the lever to rotate relative to the suspension of the lever in the vertical direction in combination with the suspension and the pivoting movement of the lever by the first shaft, which is a rotational axis.

For the longitudinal extension of the lever, approximately two shafts, ie the first shaft and the second shaft, are arranged at approximately the same height. However, offset arrangements are also possible.

In the case of an automatic transmission of a vehicle, for example, the two swivelable shafts can be mounted so that the gearshift lever moves in one rotational direction to various movement positions (P, N, R, D), Can be moved to the manual movement mode or the automatic track by the pivoting movement by the second shaft which is the axis of rotation.

According to the concept of the invention, the second shafts are oriented substantially perpendicular to the first shaft, and the suspensions are connected to each other in the axial extensions for the purpose of being implemented so that the suspension is rotatably installed with respect to the first shaft. And two bearing bolts of the first shaft opposite to each other. For this purpose, on the opposite end sections, the suspension preferably has bearings in which the end sections of the bearing bolts of the first shaft face each other are arranged. The bearing bolts of the first shaft or the first shaft are not formed continuously, ie the suspension is located between the bearing bolts of the first shaft or the first shaft, and the second shaft is between the two end sections of the first shaft. Mounted on the bearings in the suspension in the interstice formed by the suspension, the longitudinal extensions of the two shafts are formed at an angle of about 90 ° with respect to each other.

According to the concept of the invention, another magnetic element is arranged on the lever at radial distance from the swiveling shaft, ie from the swiveling first shaft and / or the swiveling second shaft, the position of the magnetic element being on the suspension It can be detected by a single magnet position sensor attached to the suspension or on the arranged circuit board. The magnet position sensor detects the pivot position or pivot movement of the lever relative to the suspension of the lever, and when properly calibrated, the position sensor, such as a rotation angle sensor, is also an algebraic sign of an electrical signal caused by a connected magnetic element. Based on the albrabraic sign or value, it correlates directly with the angular position or position of the lever.

The magnet position sensor may be arranged on a circuit board face formed perpendicular to the axial extension of the second shaft. The pivoting movement of the lever relative to the suspension thus causes the pivoting of the lever parallel to the circuit board plane. Based on the change generated with respect to the distance between the magnet element arranged on the lever and the position sensor arranged on the circuit board and on the basis of the electrical signal that can be obtained with the change, the device is basically a single position sensor and a rotation angle sensor. It is possible to implement an accurate measurement of the position and angular position of the lever using.

The magnet position sensor and the rotation angle sensor presented in accordance with the present invention provide two sets of individual magneto-sensitive elements in order to be able to ultimately provide an improved malfunction prevention and redundant sensor for rotation angle detection. It can have

Furthermore, according to a particularly preferred embodiment according to the invention, three or more rotation angle sensors provided for detecting the position of the lever are adjacent to each other along the direction of rotation of the lever on the suspension or on the circuit board fixed to the suspension. Are arranged. Here, in particular, the plurality of rotation angle sensors formed directly and adjacently adjacent to each other utilizes a virtually constant radial component in a direction of rotation of the lever, ie substantially constant radially relative to the pivoting movement of the lever. On the suspension or on the circuit board exclusively arranged adjacent to each other.

In this specification, in particular the magnet elements arranged on the lever and connected with the rotation angle sensor are configured to simultaneously operate two or more rotation angle sensors arranged adjacent to each other in the direction of rotation. In the event that one of the rotation angle sensors is completely malfunctioning or fails, the above is converted to an extra rotation angle sensor. Still, the position of the rotation lever inside the suspension allows the information to be reliably and clearly determined by other rotation angle sensors.

Further objects, features as well as the advantageous effects of the invention are described in detail with reference to the embodiments described in the drawings. In this specification, all features presented in meaningful combinations in the form of text or images constitute the subject matter of the present invention. In addition, the foregoing applies irrespective of the claims and claims mentioned later.

1 to 3 illustrate a first embodiment of the invention for the automatic transmission of a motor vehicle, in which the gearshift lever 1 and the selector lever are arranged with respect to the first shafts 2a and 2b in two different directions. 2 pivotally mounted about the shaft (5). In general, two different faces of rotation are called so-called automatic tracks in which the lever can be moved into the movement position (P, N, R, D) and Form a manual shifting mode. The lever 1 extends through a slot 16 provided on the upper section of the suspension 3, which suspension can be formed of a gearshift lever cage and which has a swivel first shaft 2a, 2b. Slot 16 having a long extension formed in parallel with
On both lateral ends of the lower section of the suspension, the suspension 3 or gearshift lever cage has bearing eyes 4a and 4b which secure the free end sections of the bearing bolt, resulting in suspension 3. The entire suspension can pivot around the first shafts 2a, 2b.
When the user applies a pivoting motion on the lever 1 with the shafts 2a and 2b as the rotation axis, the suspension 3 is moved together because of the forced guidance provided in this direction. As shown in FIGS. 2 and 3, a circuit board 15 is arranged on the suspension, and flange-shaped extensions 17, 18 are arranged in the lower section of the circuit board located at the bearing bolt height. On the extension one or more elements of the rotation angle sensor arrangement are provided, and the magnet elements 6a, 6b of the rotation angle sensor arrangement are arranged in the free end section of the bearing bolt.
Therefore, the turning movement of the suspension 3 corresponds to the corresponding turning movement of the circuit board 15 arranged on the suspension and the rotation angle sensors 7a and 7b arranged in the region of the flanged extensions 17, 18. Causes a turning movement. Opposite to the rotation angle sensors 7a, 7b each bearing bolt has magnetic elements 6a, 6b, which magnetic elements 6a, 6b generate a magnetic field and as shown in FIG. It may have a circular shape. The angular position of the magnet elements 6a, 6b can be converted directly into a distinct electrical signal by means of the rotation angle sensors 7a, 7b which face the magnet elements 6a, 6b.
In particular, the magnetic elements 6a, 6b are formed of permanent magnets. However, depending on the required shape, it may be provided in the form of an electro-magnet.
Instead of the embodiment in which the rotation angle sensors 7a, 7b are arranged fixed to the suspension 3, and the magnetic elements 6a, 6b generating a magnetic field are arranged on the shafts 2a, 2b The opposite configuration is also possible. That is, the rotation angle sensor and the associated circuit board are arranged fixed with respect to the support structure of the motor vehicle, whereby a magnetic element generating a magnetic field is mounted on a lever 1 pivotally mounted or for example a gearshift lever carriage. As such, it is arranged on a suspension 3 connected to the lever 1.
On the end section of the suspension located at the bottom in FIGS. 1 and 2, as best shown in FIG. 3, the gearshift lever cage or suspension 3 is between the two free ends of the shafts 2a, 2b. And a swiveling second shaft 5 which is formed parallel to the suspension and which is fixedly coupled to the lever 1. As shown in FIGS. 6 and 7, on the section of the lever 1 towards the circuit board 15, another permanent magnet 8 is connected to the second shaft 5 and the first shafts 2a, 2b. Provided at a radial distance from the position, in the case of a pivoting movement with the second shaft 5 as the axis of rotation, the position of the magnetic element is arranged on the other sensor elements 10, 11, 12, 13, 14).

The pivoting movement with respect to the first shafts 2a, 2b, which can be detected by the rotation angle sensors 7a, 7b, is characterized in that the lever 1 It can be implemented completely independently for each position of). As a result, as shown in FIG. 1, the gearshift lever cage 3 is mounted to be fixed against the tilting movement of the lever 1 in the lateral direction. Of course, the positioning of the lever 1 pivoting with respect to the second shaft 5 can also be implemented independently with respect to the assumed swiveling position of the gearshift lever cage 3. .

The measuring device shown in FIG. 4 provides rotation angle sensors 7a, 7b arranged substantially parallel to the circuit board faces 15, 17 and formed flat. The magnetic field, which may be generated by the magnetic elements 6a, 6b, may be split in the rotation angle sensors 7a, 7b into mutually orthogonal magnetic field components formed on the surface of the circuit board. The rotation of the magnet elements 6a, 6b around the shafts 2a, 2b provides information about the specific angular positions of the magnet elements 6a, 6b in the orientation of the rotation angle sensors 7a, 7b. Is converted into a corresponding change in the measurable magnetic field component.

An optional or additional device according to FIG. 5 shows a sensor 9, the surface normal of which is formed in the radial direction of the swivel first shafts 2a, 2b. Here, it is also possible to clearly correlate with the angular position of the magnet elements 6a, 6b based on the electrical signal that can be generated by the sensor 9, assuming that proper calibration has been made. In this case, however, the magnetic field present in the sensor 9 and emerging from the magnetic elements 6a, 6b is not divided into various magnetic field components in the plane of the sensor 9, but instead in some longitudinal direction in FIG. 5. Only the magnetic field components formed are determined in terms of their orientation and magnetic field strength.

A very similar situation also appears in the relative arrangement of the permanent magnet 8 arranged on the lever 1 and the position sensor 10 connected with the permanent magnet. Here, it is possible to correlate the measured signal precisely with the corresponding rotational position of the lever 1, in particular on the basis of the amplitude of the measured signal obtained and assuming that the calibration has already been made.

Finally, FIG. 7 shows another alternative embodiment, in which a plurality of rotation angle sensors are arranged adjacent to each other, the sensor elements being physically separated from each other, in particular individual Hall sensors. Are arranged on a circuit board 15, the circuit board face of the circuit board extending in parallel with the rotation face of the lever 1 with respect to the second shaft 5. The sensor elements 11, 12, 13, 14 formed in a switched manner are permanent magnets 8 and the sensor elements 11, 12, such that they are operated in duplicate at respective times at predetermined positions P1, P2, P3. The alternating configuration of 13, 14 is achieved. For example, if the lever 1 is in the P1 position, two sensor elements 11, 12 generate an electrical signal. In the P2 position, the two sensor elements 12, 13 are activated, while in the P3 position of the lever 1, the two sensor elements 13, 14 generate a signal that can be electrically measured. do.

If one of the sensors fails, precise and clear information can then be obtained regarding the current or moving position, based on the switching state of the other sensors.

The truth table presented below illustrates this. For example, if sensor 12 fails at the P2 position, then other sensors 13 continue to emit a signal. Because the sensor 14 does not currently generate a signal and because of the additional information presented that the sensor 12 has failed, the other three working sensor elements 11, 13, 14 are P1 which is the current position of the lever 1. , P2 or P3 can be determined accurately and clearly.

8 shows another embodiment of redundant detection of the angular position of the lever 1. Contrary to that shown in accordance with FIG. 4, the four sensor elements 21, 22, 23, 24 shown in FIG. 8 by way of example are arranged above each other as well as adjacent to each other in a substantially rectangular shape with respect to each other. Even in the case of FIG. 8, the permanent magnet 8 attached to the lever 1 can be detected by two or more of the sensors 21, 22, 23, 24, yielding a truth table which will be described later in the final analysis. .

In addition, even if the electronic system cannot indicate which sensor has failed, a signal that can be clearly correlated may be generated in this case as well.
